A prospective study of antenatal anxiety and depression in pregnant women with polycystic ovary syndrome.

BACKGROUND

Women with polycystic ovary syndrome (PCOS) experience higher rates of depression and anxiety. There is limited research relating to perinatal mental health in women with PCOS. Studies suggest PCOS is associated with a higher prevalence of perinatal mental health disorders. Perinatal guidelines currently do not recognise PCOS as a risk factor for perinatal mental health disorders. We aimed to prospectively assess the prevalence of mental health disorders in pregnant women with PCOS.

METHODS

Consenting pregnant women, with and without PCOS, were invited to participate. Standardised validated questionnaires were carried out including Generalised Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9) and Edinburgh Postnatal Depression Scale (EPDS).

RESULTS

Fifty-one with PCOS and 49 without PCOS responded. Pregnant women with PCOS had a higher mean (SD) anxiety score (GAD-7) than those without PCOS (8.2 [6.7] vs. 5.89 [4.7], = 0.04). Pregnant women with PCOS had higher mean (SD) depression scores than those without PCOS on EPDS (9.1 [6.4] vs. 6.4 [4.5], = 0.02) but not PHQ-9 score (median (IQR) 4 (3-9) vs. 4 (2-7.5), = 0.25). Women with PCOS were more likely to experience moderate/severe anxiety (PCOS 34%, control 20%) and moderate/severe depression (PCOS 34%, control 20%) symptoms than women without PCOS. Twenty-nine percent of pregnant women with PCOS had an EPDS score >13 showing significantly higher rates of severe depression (PCOS 29%, control 12%, = 0.03).

CONCLUSION

Our findings suggest a higher prevalence of perinatal depression and anxiety in women with PCOS. Our findings may suggest increased need for screening for mental health disorders in women with PCOS.
